Altimeter METER

Meter Altimeter finished. Initially I tried a 1/10 geared stepper motor but that turned out to be too slow for any kind of quick descents. So I had to split the needles in two using one stepper motor per needle. Works perfectly. The QNH is set in the gauge itself not via a potentiometer. The entire construction holding both stepper motors is being moved when turning the QNH knob.

Needle put into a 0,8mm brass tube.
Pushing in the needle
Ready for final assembly. Note the original Lufthansa sticker on top
